Be it known that we, ENRIQUEFG. Donnrne HARMSEN and MATHEW Knmm'rovi;

citizens, respectively, of Peru and Austria,-

and residing, respectively, at Hacienda Sausal, via Trujillo, :Peru, and Cuzco, Peru, have invented new and: useful Improve ments in Safety Boxes, of which the follow ing is a specification. 1 v 1 n Our invention relates tosafety. packing, boxes and is intended to provide a receptacle into which may be packed coin, bullion, jewelry or other kinds of valuable articles or goods, for transportation with little dan-,

ger of'subtle subtractions or substitutions f of the contents. Another object of our invention is toconstruct a box having; parts of its structure transparent and easily i accessible I whereby" the contents of the box are immediately visible.' At 'certainstages of the transportation or handling the shipment may be checked without unpacking and with practically no loss of time. A further-objectbf our invention is to providea packing box of substantial and economical construction and one that will give the. utmost securityto'the consignor carrier and. consignee; The construction of boxes specially adapt; ed for theuse of traveling agents. and jewelers for readily displaying their wares is also contemplated.- Other objects ofour invention are'poin'ted out andIdeScIibed: in the description con tainedinrthe specification that-follows. 1

the accompanying drawings, in: which like numerals represent corresponding parts.

This leaves the upwardly *projbctinggcentral 7 piece 23 which is recessed throughout its length-near its juncture with the body per-- tionjof-end piece 114; Inthisrecess is fitted.

and; secured a strip which forms with v the upper and lower walls of said recess a pair of' para'll'el grooves 19,120. Arectangular a recess-is alsofcut along each inner edge of the-end pieces ll janda holder 16 having spaced parallelgrooves l7 18 is'- secured .in 'eachg-of these recesses.v

' ;7The lidj frame of the box consists of two simi ar-is rips fi h v ng holes 3', wf i m d near each end adapted to align with holes 13 dnd l'sce e e ubu ar b t 21, washers and fasteningscrews 24 I-(see Fig. 8). The tubular bolt 21 is internally threaded and the frame of thebox is firmly held together by the screwslfl l' which fit the corresponding threads er" the tubular bolt. The holes 13 are counter-sunk to a sufficientv depth to allow the heads of the fastening screws 24 to be entirely "hidden by the seals 37. Each lid strip is recessed at right angles and eachreeess isfitted'rwith nietallicstrips ofthe'end pieces; Theftransparent plates 30 arethen placed. in the grooves 12 and. 18 which are now at rightfangles andhin the saineplane. Thefperforated steel. plates or gratings 35 are likewise inserted in the outside grooves 11 andll. The lid strips 15 are placed in position with the h'oles13 at one end engaging the two bolts '21 which have been inserted through the base' and end pieces The p1ates31 and 36 are placed in the grooves 29 and 28 of the lid "strips and pushed through these grooves until they en gage the corresponding grooves'ofthe end piece 14. 'The in aterial'to be shipped, such as bullion, is now placed within the box and the closure end it is placed in position-so that'itsgrooves engage both the side and topplates. The two remaining bolts-21 are then inserted' through i the registering holes l3,l3 and 13. The screws-"24;; are turned and their threaded connection with the tubular bolts serves to tighten them against the washers 25 and hold the-frame work rigidly together. -Finally sealing wax is applied" about the screw-head's," thereby forming the seals 37" and the box isQfully prepared for" shipment. It will be noted that when the box is securely. closed "its contents remain in full view of the'in terested parties and it cannot be opened without breaking the seals and partially disassembling. i The steel strips above referred to are preferably secured to the frame by screws inserted through said strips into the parts of the box to which said strips are secured so that when the box is built up these screws are not accessible.

The box may have an auxiliary cover if desired, such as indicated by numeral {40. The cover" comprises atop 4:1 for covering the top of the box and two side pieces 42 forcovering the sides, thereby hiding; the contents of the box from view when the cover is closed and furnishing a further protection from external injury. The top 41 and sides 42 are secured together in any convenient manner as by screws or nails and the top is'connected to one of the end-pieces 14:

rename closed position by apad lockill. Th box is al -Meier cur'edtt'ieach endp'iece 14 so that the box p edinfith'handle's 45 pivotally sepan be handled easily and carried without injury. For convenience each box may also ,havei attachedtomthe-outside cover or other suitable place a small plate 46 on which the exact weight of the empty box is marked.

is evident that, man .inodificati-ons' iof the box illustrated'f niay be constructed. 1 For instance, some o the transparent plates .i'nay be omitted. ii articles. within the box are insuch large piecesfthat theycannot. pass through theaapertures of the protecting plates.- Further, the: top grating may be omitted when used in conjunction with a cover, which structure will give ready 5 access to the interiorof the box by removing one: lid strip and also afford aclearer view of the contents. Such a. box orcase is specially adapted for the use of travelingagents and 'ewelers since when closed the valuable contents are hidden from View whilezupon removing the cover the exhibits are readily visible; lhe box frameainay also be con struoted of material other than wood sueh as steel, leather, or any otherinaterialthat is best suited'for the goods toQ-be handled.

' As the contents oflthe box can be seen at will, any person whoreceives in due. course or" business is enabled tosee with slightex. aminationthatthe contents are really what they purport to be, sothat!previoussubstitu tions or subtractionsmaybe readilyedef tected; If it is found at astation that sub; stitution has taken place or the. contents have been otherwise 1 tampere'dwith circumstances would naturally point to. the person who had charge ofithe box. before this fact was reported.

As stated above, each: box is marked. with the exact weigl-it when empty whichniayv assumed in this case to be three. kilograms. Assume also that on weighing the samebox containing pounds sterling aweightof 8.5 kilograms is found, then the weight. ofthe gold contents is 5.5. kilograms net-and asv suming that thev weight of each .coinis 7K5 grams, the contents of the box should-be 733 pounds sterling. -When the box is to-be used for the shipment of standardartieles of uniform weight atable 4:7; is attaohed to I the actual condition or contents when articles are standard and uniform.

It may be noted that the box may be readily disassembled into units and thus returned to the point of shipment, thereby occupying less cargo space than if shipped empty in built-up condition.

' Having described our invention, what we claim as new and desire to secure by Letters Patent, is

1. A packing box having a rigid frame, transparent plates inserted in theframe and gratings for protecting saidplates.

2. A packing box having a frame comprising a base, end pieces and lid strips securely connected together; transparent side plates supported by said frame and a transparent top-plate maintained in position by said lid strips.

3. A packing box having frame members comprising a base, end pieces and lid strips; transparent side plates supported by said frame members, a transparent top-plate maintained in position byfsaid lid strips,

internally threaded tubular bolts, and screws engaging the threads of said bolts for firmly holding the frame members together.

4. A packing box having a frame of opaque material, transparent side plates and the in closedposition.
